The Psychological Reality of the Apparent Perceptual Dimensions of the Alphabet.
Redalia, Barbara
An experiment using an analysis of the distinctive features of lower case letters of the English alphabet to predict high- and low-confusible alternates for each letter was reported. Ten disadvantaged 5-year-old Negro children served as their own controls, circling in booklets the letters seen after a 1-second presentation by memory drum. The memory drum tapes used five random orders and presented each letter twice. The letters appeared in the response booklets once with high-confusible alternates and once with low-confusible alternates. Mean errors for the high-confusible condition equaled 7.7, for the low-confusible condition 2.1, significant by t test at the .01 level. The concepts most frequently involved in errors were (1) location in space (b - p, d - q, f -t) and (d - b, p - q) and (2) vertical extension of a letter part (d - a, q - a, n - h). Letter pairs with the lowest percentage of distinctive features were those most frequently confused. Tables, references, and an appendix are included. (Author/WB)
